To all lwluzwn z't may concern: f

Be it known. that l, `lllaira'nn A. Doneer, Va citizen of the United States, residing at Columbus, in the county. of FranklinI and State of Ohio,'have invented certain new and useful Improvements in 'Mine Cars, of which the following is a specification, referenoe being had therein to the accompanylin drawing.

he invention principally relates to the improvement of the frame members, body, wheel-carrying mem-bers and draft elements of mine cars, as more particularly hereinafter set forth and claimed. l f

With such objects in view,'as well as other advantages which may be incident to the use of the improvements, the invention consists-,f in 'the parts and combinations thereof hereinafter set forth and claimed, with theunder-- standing thatthe several necessary elements constituting the same may be varied in proportions and arrangement without departing. from .the nature and scope of the `invention.

ln order `to make the invention more j clearly lunderstood there are shown in the been made the subject of. illustration. 1 ln wtf).

accompanying drawings means for carrying the same into practical edect, without limit;-

-ing the improvements,I in their useful applif cations, to the particular constructions' j which, `for theA purpose'of explanation, havethe said drawings z- Fig. l is" aside elevation of a mine car embodying the invention.

Fig.'2 is a bottom plan view of. the same.

Figs. 4 and 5 are end elevations of the car frame and body. v

. Fig, 6 is a vertical sectional view of a portion of the car body, illustrating the relation thereto of the brake lever.

Referring ,to the drawings, 1 indicates the wheels, ordinarily four in number, carried onthe ends of axles 2 which passA through. tubular' bearings 3, which bearings are 'integral with 'a bottom lbody-supporting an'd Iaxle-carrying frame. of two longitudinal side members t and cross 'llhis frame consists members 5, whichl together with the bearing sleeves 3 are ordinarily cast in one piece.

extends from end to end ofthe car approxie mately at the level of the floor thereof and formed at each. end at 7 with holes for cou-` .ing members 1li and uppervertical side members 15. These side portions fof the end frame are attached to thebottom bars '12 by vertical tenons 16 which pass down through openings 17 in said bars 12 and are held in place `by pins 18, or equivalent means,

engagingnnder the bottom bar. By this construction a knock-down mine car is or may be provided which can be easily transported and assembled at will.

Each end frame is of angle formation, the bottom bars 12 being formed withhorizontal llanges 19 which extend inward under the ttl.

bottom boards, and wit-h vertical flanges 20 which strengthen the bottomfbars for pulling and buling strains. vlheupper members of theend frame vare formedwith longitudinal yflan es 21 against which the outer.

surfaces of t e side boards en age and with vertical flanges 22 against w ich the ends of said boards it. The end boards are se- .cured in place` to the flanges 22 by bolts 23.

The bottom bars 12 are projected outwardv vto form bufng and coupling elements and,

are -vertically perforated to correspond with fthe coupling pin holes 7 lln addition to the ttl the side boards are secured, these center posts having depending tenons 26 which ass down through openings -27 in the w eel frame and are held in place by pins 28.

With the wheel frame may be combined one or more cast metal brackets 29, of angle form, which brace against the wheel frame and are secured to the bottom of the bodyl by bolts 3 0, the central bolts preferably passing through the draw-bar 6, so. that hauling strains may be directlyapplied to thev whee frame4 independently of the bottom ,bodyf elements of the nu The middle center posts 25 have attached".

thereto at one side of the car vertical guide rods 31 on which works vertically a brake y erably connected [wit b1ock'32 formed to be applied to the upper and inner sides of the wheels. This'brake block is operated by an angle arm 33 pivotally mounted at 34 on the wheel frame by means of cast lugs 35, said arm being pivoted at 36 to an arm 37 depending from the brake block.I The upper end of the arm 33 has pivoted thereto at 38 a link 39, said link being operableby a hand lever 40 pivoted at 41 to the car body and extending up through a slot 42 to the interior of the latter at one side of the same. Strengthening plates 43 are preferably applied to the side boards at the top ofthe same at points between thel end frames and the center posts 25, said plates having pivotally boltedthereto at 44 vthe ends of a yoke bar 45 which extends transversely across and is attached to the top4 of the end 'gate or dumping' door 56 (Fig. 4). This door is further supported by an inclined. yoke bar 46 which extends transversely across the middle or lower part of the door at the outer side of the same and the ends of which extend longitudinally of vthe car and are bolted to the bar 45 at 47.

This pivotal mountin of the door 56 is prefthe side posts 25 by diagonal braces 48`which are bolted to the plates 43 at 44 and are bolted to the side frames or center posts at 49. On the front face of the door is also applied a vertical strengthening and door-actuatingbar 50 which is secured by bolts 5l to the doorboards and to the transverse portion of the bar 45, and to the transverse portion of the bar 46; and I may also apply vertical strengthening members of similar character,

end of the car (Figg) these bracing members may be omitted, but in that case a transl verse bar 54 is combined with and bolted to the end frame and end board at `or about the top of the latter.

yThe door-actuating bar 50 isformed .with a hook 57 by means of which the door may be swung upon the pivots 44 to ldump the car, or b which the door may be held up while the ront end of the car is tilted down.

The bottom or buffer bars are or may be cast with an upwardly extending coupling element 55 having an end opening for the coupling link and vertically perforated for the in 8. y

T ere is thus produced a mine car frame and body of very strong construction and whichmay be very economically built and repaired, and the strainsf-o' hauling and .buing are so transmitted that they do not deteriorate the weaker and ordinarily wooden parts of the c'ar bod v The ear is thus made mines, and the metal portion of the car is minimized, and is also practically indestructible.

Among other advantages of making the wheel frame independent ofthe end frames, which construction is permitted by the use of the central through draw-bar, is the result that, without change of most of the metal parts, cars may be varied in longitudinal dimensions as may be required, either when they arebeing built or when they are being repaired.
